Description

Wind light mutual complementing is from net type electricity generation system

Technical field

The utility model relates to a kind of electricity generation system, relates in particular to a kind of wind light mutual complementing from net type electricity generation system.

Background technology

Enter 21 century, energy problem has become the economic subject matter of restriction.Along with rapid economic development of China, also vigorous further to the demand of the energy, China also rises to and is world's second largest energy resource consumption big country.Yet the excessive exploitation of conventional energy resources such as a large amount of oil, coal, natural gas has made China begin to face serious energy crisis.Moreover, in the use of conventional energy resource, caused a large amount of pollutions.As gas purgings such as CO2, SO2, make China become one of the most serious pollution big country in the whole world.Along with the enhancing of people's environmental consciousness and the uncertainty of energy access, the development and utilization of new forms of energy is extremely urgent.Hold and Japan causes under the influence that Fukushima nuclear leakage incident caused because of earthquake along with country's success of 12, in other new forms of energy, the development and use of solar energy and wind energy will be subjected to the favor of each row all circles.

In new energy field, the development of exploitation level of solar energy and wind energy is the highest, technology the most ripe, most widely used general, have the business development potentiality most.But solar power generation and wind power generation all can be subjected to the zone or the influence in season, under the situation of pure solar power generation or pure wind power generation, can cause the system capacity supply unstable.In remote districts, if just not too reasonable with mains supply: 1, electrical network cost cost height for some equipment can move; 2, the idle work power consumption is big; 3, long distance is carried the destruction that subjects to nature and human factor; 4, difficult in maintenance and cost is high.

Summary of the invention

Therefore, at the problem of above-mentioned existence, the utility model provide a kind of reasonable in design, power supply safety is reliable, the wind light mutual complementing of easy to maintenance, long service life is from net type electricity generation system.

For achieving the above object, the utility model is by the following technical solutions: wind light mutual complementing is from net type electricity generation system, comprise photovoltaic module, wind turbine generator, rectifier, wind light mutual complementing controller, batteries, inverter, described photovoltaic module, its current output terminal is connected with the current input terminal of wind light mutual complementing controller;

Wind turbine generator, its current output terminal is connected by the current input terminal of rectifier with the wind light mutual complementing controller;

The wind light mutual complementing controller, its current output terminal is connected with the current input terminal of batteries;

Batteries, its dc output end are connected with DC load with the direct-flow input end of inverter respectively;

Inverter, its ac output end is connected with AC load.

Preferably, described inverter is the transless inverter.

By adopting technique scheme, the beneficial effects of the utility model are as follows: the utility model is with the generating that combines of photovoltaic module and wind-driven generator, can make full use of the generating of luminous energy and wind energy resources, not only can reduce the not enough or unbalanced situation of the supply of electric power of adopting the single energy to cause, but also saved conventional energy resource, reduced environmental pollution; System can regulate and control the electric energy that photovoltaic module and wind-driven generator send efficiently, on the one hand adjusted electric energy is sent to DC load or AC load, on the other hand the characteristic curve of unnecessary electric energy by storage battery charged to batteries, the wind light mutual complementing controller effectively protects storage battery not overcharged; Wind light mutual complementing of the present utility model is reasonable in design from net type electricity generation system, power supply safety is reliable, easy to maintenance, long service life, and efficiently solve the powerup issue of power consumption equipment from far-off regions, its system cost is powered far below the electrical network long-distance cable, use not limited by the region, be specially adapted to that some are arranged on by the expressway, the more unattainable advertising equipment of the first-class mains supply in mountain.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

Embodiment: please refer to Fig. 1, the utility model embodiment discloses a kind of wind light mutual complementing from net type electricity generation system, comprise photovoltaic module 1, wind turbine generator 2, rectifier 3, wind light mutual complementing controller 4, batteries 5, inverter 6, the current output terminal of described photovoltaic module 1 is connected with the current input terminal of wind light mutual complementing controller 4; The current output terminal of wind turbine generator 2 is connected with the current input terminal of wind light mutual complementing controller 4 by behind rectifier 3 rectifying and voltage-stabilizings; The current output terminal of wind light mutual complementing controller 4 is connected with the current input terminal of batteries 5; The dc output end of batteries 5 is connected with DC load 7 with the direct-flow input end of inverter 6 respectively; The ac output end of inverter 6 is connected with AC load 8, and described inverter 6 adopts the transless inverter, exports to AC load 8 again after the direct current that this inverter 6 is exported batteries 5 converts alternating current to.

Wind light mutual complementing of the present utility model from the operation principle of net type electricity generation system is: the alternating current of wind turbine generator 2 outputs becomes the adjusting and control of direct current by wind light mutual complementing controller 4 of direct current and photovoltaic module 1 output by rectifier 3 rectifying and voltage-stabilizings after, output galvanic current, wind light mutual complementing controller 4 are sent to adjusted direct current output DC load 7 or are converted to alternating current output through inverter 6 on the one hand and be sent to AC load 8; On the other hand the characteristic curve of unnecessary energy by storage battery charged to batteries 5, when electricity can satisfy loading demand, wind light mutual complementing controller 4 was sent to load to the electric energy of batteries 5 again, had effectively guaranteed the continuity of power supply.After batteries 5 was full of electricity, wind light mutual complementing controller 4 protection batteries 5 were not overcharged; After the electric energy that batteries 5 stores had been put, wind light mutual complementing controller 4 protection batteries 5 are not crossed put, and effectively protects batteries 5, prolongs the useful life of batteries 5.

Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, the technical staff in relevant field is not breaking away under the spirit and scope of the present utility model, and various conversion of making and variation all belong to category of the present utility model, should be limited by each claim.
